I am new to the site I think I am in the right spot for tech help. I have a 1994 3.8 convertible, I am just about done on a build of a 1989 5.0 HO small mods gasket match, 1.7 rockers and long tube headers. i could use any thoughts on what computer to use I think the 1994 5.0 was DSI (the 3.8 is) and the 1989 is not? so should I find a used 1995 or 1989? If you have any other thoughts that would be great.
